Just had car back from Diagnostics and apparently I have a P0406 Exhaust Gas Re-circulation Sensor A circuit high.
I have tried taking it off and cleaning it and also cleaning the MAF sensor before admitting defeat and taking it to get checked out today.
My question is does the EGR have a seperate sensor or does the fault code I have been given mean I need a new EGR valve as the guy at the ford garage didnt think there was a seperate sensor just the EGR valve, they gave me a price of £146 for the part which I thought wasnt too bad.
Any help would be great
Fault Code P0406
